development of the business, the increasing micro-services and indicators have brought great challenges to the monitoring platform. The Monitoring team needs to weigh constantly on the issues of open source vs self-research, flexible vs stability, to meet the needs of rapid development. This time we will share our white-box surveillance thinking under microservices and how to place open source technologies such as the popular spring Cloud,k8s,prometheus
Daemonset is a new resource object in the kubernetes1.2 version that manages only one copy of the pod on each node in the cluster.
This usage applies to scenarios where a glusterfs storage or ceph storage daemon process is run on each node. Run a log capture program on each node: Fluentd or Logstach. Run a health program on each node to capture performance data for the node, such as Prometheus Node exportor, COLLECTD, New Relic agent, or ganglia gmo
First, the environment:
10.1.16.65 CentOS7.2 (PMM Server)
10.1.16.52 CentOS7.2 MySQL 5.7.16-master (PMM Client)
10.1.16.53 CentOS7.2 MySQL 5.7.16-slave (PMM Client)

Check the iptables of the three servers to see if SELinux is closed or in permissive
Third, installation
1. Install PMM Server on 10.1.16.65:
At present official PMM only Docker mirror, so need to deploy first Docker

This series of questions leads us to the idea of "creating customized storage, field computing, and the engine that provides query services," which is Prometheus (see Figure 6).

Separate application test environment, import online data into the test library, do several more online analog switching operations.
It is best to do grayscale switching and release verification, let some users first use the new application, verify OK after the full amount of switching, such as the new United States in accordance with the Office network and external network to divide user groups.

Overall, the new United States service is

Q: Since it is the package, the bottom with Mesos than kubernets is not much flexibility, right?
A: For the PAAs platform, we want only the resources to dispatch this function, other functions we still want to be able to implement, and Mesos is focused on scheduling resources, and has experienced a lot of levels of testing. And Kubernetes currently provides a lot of services, we do not need,
